> If the license to lend is included in a physical copy, not in a digital, how does that explain the same pricing for either in a lot of cases.

The pricing is entirely up to the creator and the publisher. No explanation is necessary simply because the price does not match your perception of value.

> Rights that were acquired trough spending a lot on legalized bribery (called lobbying).

Rights in this case are what I consider natural rights.

While I agree there are problems with it, I do not agree that one problem is that people who buy physical copies of a work should be allowed to make one digital copy and lend it out ad infinitum to people, whether it be one at a time or not.
